🌱 How to Care for Silver Sparkle Pilea to Prevent Southern Blight?

💧 How to Water

Water when the top 1-2cm of soil has dried out, soaking thoroughly until water drains from the pot, then discard excess. This plant is sensitive to both overwatering (root rot) and prolonged dryness.

☀️ Lighting

Bright, indirect light is ideal, such as near an east-facing window. Avoid direct sun, which scorches the delicate leaves; too little light causes leggy growth and dull color.

🪴 Ideal Soil

Use a light, well-draining mix, e.g. 3 parts peat-based potting soil to 1 part perlite, to keep roots aerated and prevent waterlogging.
